Definitions

  • the present disclosure relates to a scouring pad for washing dishes. More particularly, the present disclosure relates to a scouring pad for washing dishes, which contains a biodegradable polymer.
  • a scouring pad for washing dishes is widely used for removing contaminants stained on dishes and the like.
  • the scouring pad is generally formed of a polymer fiber. Accordingly, when the scouring pad is discarded after it is used, there may incur an environmental pollution problem according to processing of a waste polymer.
  • a scouring pad for washing dishes manufactured by using an environmentally-friendly polymer have been developed.

  • FIG. 7 a shows a state in which oil is adsorbed to the sample according to the example when taken from a top
  • FIG. 7 b shows a state in which oil is adsorbed to the sample according to the example when taken from a side.
  • a scouring pad for washing dishes comprises (a) a plurality of degradable polyester divided yarns 20 heat-treated at 120° C. to 170° C. and (b) a plurality of degradable polyester filament yarns 10 , wherein the individual filament yarns 10 are aligned in parallel to each other and the individual divided yarns 20 are positioned between the adjacent two filament yarns 10 and are connected to the adjacent two filaments 10 .
  • the filament yarns 10 correspond to basic frames of the pad, and the divided yarns 20 are positioned next to the filament yarns.
  • a fiber may be divided into cotton yarn and filament yarn according to a length and a manufacturing method thereof.
  • the cotton yarn is manufactured by performing a cotton carding process of evenly engaging and arranging single fibers, such as cotton, linen, and wool, in a direction of a fiber axis several times, and twisting the single fibers at the last stage.
  • the filament yarn is manufactured by combining several strands of infinitely long fibers (filament yarn), such as a silk fiber or an artificial fiber, side by side, and twisting the fibers.
  • biodegradable polyester may be used as the filament yarn.
  • the biodegradable polyester may be derived and obtainable from nature, such as biomass, and thus is a naturally degradable environmentally-friendly material.
  • poly-lactic acid may be used as the biodegradable polyester.
  • the biodegradable polyester filament yarn may also be used for forming a basic frame of the scouring pad, but may be used for forming a border sewing thread.
  • the border sewing thread formed of the biodegradable polyester filament yarn is more environmentally-friendly, compared to a border sewing thread formed of a non-biodegradable fiber, such as nylon.
  • the filament yarn forms the basic frame
  • the biodegradable polyester particularly, poly-lactic acid
  • a thickness of, for example, 350 to 650 deniers When the thickness of the biodegradable polyester filament yarn has lower than 350 deniers, it is difficult to maintain an intensity of the biodegradable polyester filament yarn.
  • the thickness of the biodegradable polyester exceeds 650 deniers, the scouring pad is stiff, such that flexibility deteriorates.
  • the filament yarn forms the border sewing thread of the scouring pad
  • the biodegradable polyester particularly, poly-lactic acid
  • a thickness of, for example, 800 to 1200 deniers When the thickness of the biodegradable polyester filament yarn has lower than 800 deniers, the intensity thereof is weak, so that there are concerns regarding unraveling of the sewing thread.
  • the biodegradable polyester filament yarn exceeds 1,200 deniers, cost is increased, thereby degrading economical feasibility, and the scouring pad becomes stiff, thereby degrading flexibility.
  • the divided yarn refers to filament yarn obtained by applying static electricity to the multifilament, and then opening the multifilament (spreading a bundle of fibers and making the spread fibers sparse) to be divided. It is more economical to make thread by dividing the multifilament as described above, compared to making thin thread from the beginning.
  • biodegradable polyester heat-treated at 120° C. to 170° C., and preferably at 130° C. to 160° C. may be used as the divided yarn.
  • poly-lactic acid heat-treated at 120° C. to 170° C., preferably at 130° C. to 160° C. may be used.
  • the divided yarn may be broken when temperature of the heat treatment exceeds 170° C., and the divided yarn may not be hard under the heat treatment at the temperature lower than 120° C.
  • the biodegradable polyester used as the divided yarn provides excellent cleaning power, and exhibits an excellent effect of forming bubbles even without abrasives. The reason seems to be that many air-contact surfaces exist between the divided yarn fibers, and that bubbles are stored in the air contact surfaces, so that the bubbles are maintained for a longer time.
  • a thickness of the heat-treated biodegradable polyester is 550 to 650 deniers, and poly-lactic acid divided yarn with 23 to 30 fils is preferably used as the heat-treated biodegradable polyester.
  • the divided yarn having the aforementioned thickness prevents foreign materials, such as rice paste, from being easily stuck in a scouring pad in a process of washing dishes, and allows the scouring pad to be easily dry and simultaneously prevents germs from easily living.
  • the scouring pad according to the present disclosure has the aforementioned divided yarn structure, thereby preventing minimal scratches on the surfaces of dishes, which are targets for cleaning.
  • the reason is that the scouring pad according to the present disclosure does not include an abrasive film, contrary to the conventional scouring pad.
  • the filament yarn may be manufactured by a common method widely known to the field.
  • the filament yarn may be manufactured by spinning a PLA fiber extracted from corn.
  • the filament yarn formed of 100% of poly-lactic acid may be manufactured.
  • the filament yarn manufactured may have excellent durability and excellent biodegradability, thereby securing basic mechanical performance as a scouring pad.
  • the manufactured filament yarn is formed of a natural component, so that the manufactured filament yarn may naturally degrade in land even when the manufactured filament yarn is discarded after it is used.
  • the filament yarn is woven to a PLA mesh net by a spinning process.
  • the divided yarn and the filament yarn are woven by a comed method, which is a method in which the divided yarns connect the filament yarns in a zigzag manner in a state that the filament yarns form a basic frame.
  • the manufactured mesh net has a shape of a checkerboard having openings (see FIG. 3 ).
  • the scouring pad manufactured by the present disclosure may have one layer, or may have a structure in which two scouring pads enclose sponge in a sandwiched shape while having the sponge interposed therebetween.
  • the sponge may be manufactured from bean produced from nature as a raw material. Accordingly, the scouring pad having the sandwiched shape may be an environmentally-friendly product.
